This paper analyzes the mechanism of the secondary ripple generation and propagation of the two-stage single-phase inverter, and applies the model predictive control to it, and adds a notch filter to improve the ripple suppression performance. Finally, the. . The cause of the secondary ripple and the mechanism of propagation was analyzed in this article. Finally, the. . Low-frequency pulsating ripples exist on the input side of a single-phase inverter, which bring some adverse effects and harm to the inverter and photovoltaic power generation system. Aiming at this problem, this paper proposes a two-modal modulation method and its MPC multi-loop composite. .

Solar inverters may be classified into four broad types: 1., used in where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral to replenish the battery from an AC source when available. Normally these do not interface in any wa.
